    摘要: A substrate provided with an alignment film includes: a substrate including an electrode on a surface thereof; and an alignment film in contact with the electrode. The alignment film contains a first polymer that contains a polysiloxane structure in a side chain and a second polymer that contains a photo-reactive group or a vertically aligning functional group. The alignment film includes a first surface that is placed on a side close to the electrode and contains the first polymer and a second surface that is placed on a side opposite to the first surface and contains the second polymer. The first polymer has a weight that is equal to or greater than a weight of the second polymer in the alignment film.

    摘要: A method of fabricating a flexible substrate assembly includes forming a first polyimide layer on a rigid support base, wherein the step of forming the first polyimide layer includes incorporating in a polyamic acid solution, an adhesion promoting agent and a release agent for achieving different adhesion strength at two opposite sides of the first polyimide layer, and forming a flexible second polyimide layer on the first polyimide layer, the second polyimide layer being adhered in contact with the first polyimide layer, and a peeling strength between the first and second polyimide layers being less than a peeling strength between the first polyimide layer and the support base so that the second polyimide layer is peelable from the first polyimide layer while the first polyimide layer remains adhered in contact with the support base.

    摘要: A high-flow polymer composition includes a polyetherimide (PEI), a PEEK-PEDEK copolymer, and optionally a poly(aryletherketone) (PAEK) other than the PEEK-PEDEK copolymer. The polymer composition surprisingly exhibits improved toughness and chemical resistance, making it suitable for the manufacture of shaped articles where a combination of high-flow, impact resistance, and chemical resistance are required.
